Answer:

(x - 3)(3x + 4)

Step-by-step explanation:

Given

3x² - 5x - 12

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 × - 12 = - 36 and sum = - 5

The factors are - 9 and + 4

Use these factors to split the x- term

3x² - 9x + 4x - 12 ( factor the first/second and third/fourth terms )

3x(x - 3) + 4(x - 3) ← factor out (x - 3) from each term

= (x - 3)(3x + 4) ← in factored form

Suppose that y varies inversely as x and that y=8 when x=3. Calculate the value of y when x= 10.

Svetach [21]

$\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}} ~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\cfrac{\stackrel{\downarrow }{k}}{x}~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \textit{we know that } \begin{cases} y = 8\\ x = 3 \end{cases}\implies 8=\cfrac{k}{3}\implies 24=k~\hfill \boxed{y = \cfrac{24}{x}} \\\\\\ \textit{when x = 10, what is \underline{y}?}\qquad \qquad y = \cfrac{24}{10}\implies y = \cfrac{12}{5}$

What is the slope of the shown picture?

elena55 [62]

Answer:

B. 2 is your answer

Step-by-step explanation:

You will use the slope formula to find the slope of the equation.

(3, 7) and (-2, -3) will be used.

7 and -3 are your y's. 3 and -2 are your x's.

(7 - (-3))/(3 - (-2)) = 10/5 = 2

B. 2 is your answer

What is the slope of the line given by the equation y=-1/3x? Entee your answer as an integer or fraction in lowest terms.

Serhud [2]

-1/3

really? it's that easy dude.

whatever number is next to x, like say, 3x, that number would be the slope, so it would be 3.

hope it helped.
